Description

Technical Field

[0001] The invention relates to the field of crushing, and in particular to a crushing device and method for secondary utilization of dog chew waste. Background Art

[0002] Dog chews are a kind of pet snack used for dogs to molar their teeth and protect their oral health. Its main ingredients are animal offal, meat, skin, etc.

[0003] In the production of dog chews, it is inevitable that some unqualified products will appear, that is, they do not meet the standards for entering the market. In order to avoid the waste of such products, they will be crushed and reused; After searching, a new animal skin crushing and impurity removal device for dog chew production was disclosed, with the announcement number: CN215940191U. The device is a crushing device for dog chew raw materials, and its main process is crushing and screening. The device is not suitable for the secondary utilization of crushed dog chews for the following reasons: Regarding the disposal of dog chew waste, it is actually a semi-finished product that does not meet the standards for entering the market. In the process of crushing it for secondary use, it is found that the waste cannot be completely crushed; This is because the internal structure of dog chews is relatively complex, and it contains a certain amount of granular meat, skin, and offal. These ingredients exist to make it easier for dogs to accept this product. If we crush it completely, we will need to add the corresponding auxiliary materials again, and it is relatively difficult to adjust the proportions of these auxiliary materials.

[0004] On the other hand, if we crush the waste into particles of specified size and then process them through heating and compaction, we can process them into qualified products without adding any auxiliary materials. This method not only simplifies the production process but also reduces production costs.

[0005] In addition, although the existing device has a screening function, it cannot effectively process dog chews that cannot pass through the sieve, which means that subsequent operations may need to be performed manually. This operation method is not only inefficient, but also difficult to ensure accuracy. Therefore, the degree of automation of this method is relatively low and further improvement is needed.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0033] For example, see Figures 1 to 13A crushing device for secondary utilization of dog chews waste includes a crushing box 1 and a feeding member 9 fixed to one side of the crushing box 1, a feeding assembly for conveying the dog chews waste is installed on the feeding member 9, a feeding hopper 2 is detachably installed on the top of the crushing box 1, and the feeding hopper 2 cooperates with the feeding assembly to feed the crushing box 1 in a directional manner; Rotate two crushing rollers 22 installed in the crushing box 1, both crushing rollers 22 are connected to a driving assembly installed on one side of the crushing box 1 through a transmission assembly, and the driving assembly is also connected to a feeding assembly through a transmission assembly; The crushing box is also fixed with a cleaning piece 23, which is used to remove the dog chew pieces stuck between two adjacent crushing discs; An inclined plate 26 is fixed in the crushing box 1 , and a discharge port 16 is opened on the side of the crushing box 1 away from the driving component. A screening component is installed between the inclined plate 26 and the crushing roller 22 , and the screening component is connected to a reflux component installed at the bottom of the feeding member 9 .

[0034] In the embodiment of the present invention, when the driving assembly is working, the two crushing rollers 22 are driven to rotate through the transmission assembly, and the feeding assembly is driven to work at the same time; The dog chew waste is transported into the crushing box 1 through the feeding assembly, and the dog chew waste is put into the feed hopper 2 after being transported to the top of the crushing box 1. The dog chew waste is positioned by the feed hopper 2 so that the dog chew waste is put into the center of the crushing box 1. After being limited by the feed hopper 2, the dog chew waste will fall between the two crushing rollers 22. When the two crushing rollers 22 rotate, the dog chews are crushed and broken into pieces, which fall onto the screening component. The crushed dog chews are screened by the screening component. The following conditions exist during the screening: Case 1: If the broken dog chew meets the breaking requirement, it will fall onto the discharge port 16 and then be discharged through the discharge port 16; Case 2: If the crushed dog chews do not meet the crushing requirements, they will be pushed to the reflux component, and the dog chews that do not meet the crushing requirements will be transported to the feeding component through the reflux component to be repeatedly fed and crushed until they meet the requirements; The invention can realize the automatic crushing of dog chews and ensure that the crushing requirements are met after crushing.

[0035] Embodiment 2 is distinguished from Embodiment 1 in that: the screening assembly comprises a screening box 20 slidably mounted in the crushing box 1, and the screening box 20 is located at the bottom of the crushing roller 22; It also includes a transmission rod 21 that penetrates the crushing box 1 and is rotatably mounted on the crushing box 1, a force block 2101 is rotatably mounted on the transmission rod 21, the force block 2101 and a force-bearing rod 24 fixed on the screening box 20, a propulsion member is installed on the screening box 20, and the transmission rod 21 is connected to the transmission assembly; A plurality of guide rods 14 are fixed at equal distances on one side of the screening box 20 facing the discharge port 16. The guide rods 14 penetrate the crushing box 1 and slide with the crushing box 1. A spring 15 is sleeved on the guide rods 14. A plug hole is provided at the bottom of the screening box 20 facing the guide rod 14 .

[0036] In the embodiment of the present invention, when the driving assembly is working, the transmission rod 21 is driven to rotate by the transmission assembly, and when the transmission rod 21 rotates, the force block 2101 pushes the force rod 24 to move in a direction away from the guide rod 14, so as to drive the screening box 20 to follow the movement, and when the screening box 20 moves, the guide rod 14 is driven to follow the movement, and the spring 15 is compressed at the same time, and when the transmission rod 21 is separated from the force block 2101, the elastic potential energy stored in the spring 15 is released to drive the guide rod 14 and the screening box 20 to reset; Among them, because the rotation speed of the force block 2101 when pushing the force rod 24 is relatively low, and the speed of pushing the screening box 20 to move is relatively slow, the speed at which the force block 2101 and the force rod 24 separate from the elastic potential energy of the spring 15 is relatively fast; Furthermore, when the speed of pushing the screening box 20 is not fast, the friction between the crushed dog chew and the screening box 20 is large, which will drive the dog chew and the screening box 20 to move together. During the reciprocating motion, the spring 15 releases the elastic potential energy to drive the screening box 20 to reciprocate at a faster speed. Therefore, the friction is not enough to make the dog chew and the screening box 20 reciprocate together, and the dog chew will stay at the current position or move back and forth a little distance and will not return to the initial position. The reciprocating motion of the screening box 20 can gradually move the dog chews away from the guide rod 14, and at the same time, the crushed dog chews are screened through the sieve holes, and those that meet the crushing requirements fall onto the inclined plate 26, while those that do not meet the requirements will move until they move to the reflux assembly; The broken dog chews can be separated through the above-mentioned motion state, and the dog chews that do not meet the breaking requirements are transported to the reflux component for re-transportation and breaking.

[0037] The pusher comprises two mounting blocks 27 symmetrically fixed to the inner wall of the crushing box 1 , between which a stripper plate 25 is rotatably mounted, on which a limit strip 2501 is fixed, and the limit strip 2501 cooperates with a limit block 2701 fixed thereon.

[0038] In the embodiment of the present invention, when the screening box 20 moves in a direction away from the guide rod 14, the dog chew fragments are driven to follow the movement, and when the dog chew fragments contact the stripping plate 25, the stripping plate 25 is driven to flip over to allow the dog chew fragments to pass through. When the screening box 20 moves back and forth and the dog chew fragments contact the stripping plate 25, the synergistic effect of the limit bar 2501 and the limit block 2701 prevents the stripping plate 25 from flipping in the opposite direction, thereby resetting the screening box 20 and the dog chew fragments stay on the side of the stripping plate 25 away from the guide rod 14; The return of the stripper plate 25 after flipping is achieved by the stripper plate 25's own gravity and center of gravity, so that the stripper plate 25 is returned to its original position when the force driving the stripper plate 25 to flip disappears after flipping, so that the dog chew fragments can only move in a direction away from the guide rod 14.

[0039] Embodiment 3 is distinguished from Embodiment 1 or 2 in that: a plurality of crushing disks 2201 are coaxially and equidistantly fixed on the two crushing rollers 22, the plurality of crushing disks 2201 are arranged at equal angles along the path line 2202, and the crushing disks 2201 on the two crushing rollers 22 are staggered. The crushing discs 2201 on the two crushing rollers 22 are arranged in the same direction, and the crushing discs 2201 include a disc body, and a plurality of crushing teeth are fixed on the circumference of the edge of the disc body.

[0040] In the embodiment of the present invention, please refer to Figure 7 and Fig.13 For the convenience of description, the crushing disk 2201 on the left is named as disk No. 1, and the one on the right is named as disk No. 2; When the dog chew waste is put in between the two crushing rollers 22 through the feeding assembly, the dog chew will first fall onto the second plate, and the dog chew waste is crushed by the relative rotation of the second plate and the first plate; Among them, the crushing disk 2201 is set at an equal angle along the path line 2202 to increase the feeding angle of the first disk and the second disk, making it easier for the dog chew to enter the crushing point, and the force point of the dog chew will gradually spread to both sides from the center point, so that the torque of the two crushing rollers 22 when rotating can be reduced to a certain extent.

[0041] The feeding assembly includes a conveying platform 8 fixed to one side of the crushing box 1, on which two No. 1 conveying rollers 19 and two No. 2 conveying rollers 1901 are rotatably mounted, the No. 1 conveying rollers 19 are arranged horizontally, the No. 2 conveying rollers 1901 are arranged obliquely, the two No. 1 conveying rollers 19 are connected by a No. 1 conveyor belt 3, the two No. 2 conveying rollers 1901 are connected by a No. 2 conveyor belt 4, and one of the No. 1 conveying rollers 19 and one of the No. 2 conveying rollers 1901 are connected by a No. 3 transmission chain 28; One of the No. 1 conveying roller 19 or the No. 2 conveying roller 1901 is connected to the transmission assembly.
